Background: Attention-deficit hyperactivity disorder (ADHD) is one of the most common psychiatric problems of adolescent and childhood. Methylphenidate is a psychostimulant drug in use of attention-deficit hyperactivity treatment as a first choice modality.Objective and hypotheses: The aim of this study is to evaluate the levels of leptin, ghrelin and nesfatin-1 in relation to slowdown in growth and poor appetite.Method: Total of 8...

Background: Deficiency of 11β-hydroxylase is the second most frequent type of congenital adrenal hyperplasia and more common in Turkey than other populations.Objective and hypotheses: The purpose of this study is to examine the spectrum of CYP11B1 gene mutations in Turkish population.Method: 17 patients from 13 families are included in this study. Diagnosis was based on virilisation and high levels of 11-deoxycortisol. 15 case...

Background: Central precocious puberty (CPP) in girls is characterized by an activation of the hypothalamic–pituitary–ovarian (HPO) axis before 8 years of age. Given the gradual awakening of the GnRH pulse generator, a spectrum of presentations has been found among girls with premature sexual development. CPP are not easily distinguished from idiopathic precocious thelarche (PT) or other intermediate positions along this spectrum. The GnRH test is the gold standard t...

Background: >There is a wide variation in the reported rate of acute adrenal insufficiency (AI) related adverse events (sick day episodes and adrenal crises) between centres.Objective: Evaluate the level of consensus on the criteria that should be considered ‘essential’ for defining and managing adverse events associated with acute AI in children.Methods: Three groups of ...

Calcineurin inhibitors (CNIs) are widely used in pediatric transplantation for prevention of graft rejection, prophylaxis and treatment of graft versus host disease. Though hyperkalemia is a common adverse effect (10-45%), alterations in renin-angiotensin-aldosterone system in CNI-induced hyperkalemia are not well elucidated. Consequently, CNIs vital to transplantation are usually switched. Here, we describe two cases with CNI-induced hyperkalemia due to hyporeninemic hypoaldo...

Background & Aim: Vitamin D-dependent rickets type 1 A (VDDR1A) is an autosomal recessive condition caused by mutation in CYP27B1, which encodes 1 α-hydroxylase enzyme that catalyzes the conversion of 25-hydroxyvitamin D (25OHD) to 1,25-dihydroxyvitamin D (1,25 (OH)2D). We are reporting 4 cases of VDDR1A due to CYP27B1 mutation initially misdiagnosed as vitamin D deficient and hypophosphatemic rickets.<p class="abstext...

Introduction: More than 1.1 million children and adolescents are living with Type 1 diabetes mellitus (T1DM) in 2019 worldwide1. Transition period is considered a crucial phase in management of T1DM, where movement of adolescents to adult health care is initiated. During this period, physical, psychological and behavioral changes may make this interval becoming more challenging by which diabetes management can be affected. HbA1c worsening was report...

Pseudohypoparathyroidism (PHP) and related disorders lead to a wide spectrum of abnormal physical characteristics, neurocognitive and endocrine abnormalities. PHP (including all subtypes), pseudoPHP, acrodysostosis and progressive osseous heteroplasia refer to heterogeneous disorders characterized by physical findings, differently associated in each subtype, including short bones, short stature, stocky build, subcutaneous ectopic ossifications, as well as laboratory abnormalit...

A worldwide increase in pediatric thyroid cancers incidence over the years has been observed. Although pediatric thyroid cancers tend to have a more aggressive course compared to adults, the survival rate is better. In this study, we aimed to examine the demographic, clinical, pathological, and laboratory characteristics, prognostic and risk factors of children with thyroid cancer.Methods: We retrospectively analyzed 39 children with thy...

Background: Mutations in CHD7 cause a rare multi-organ system disorder, CHARGE syndrome (CS). Genital hypoplasia has been described in 60-80% of reported cases because of idiopathic hypogonadotropic hypogonadism (IHH), which is a result of inadequate GnRH secretion in the hypothalamus. Correspondingly, IHH and anosmia are expected in cases with CHD7 mutation. However, due to the phenotypic spectrum of CHD7, mutations have also be...
